Creatinine is a byproduct of metabolism that is generated in normal muscle activity. Healthy kidneys filter creatinine from the blood and remove it through urine. When the kidneys aren’t working as well, or the body is temporarily influenced by things like dehydration, heavy exercise, or certain medications, creatinine can accumulate in the bloodstream. Elevated creatinine levels do not necessarily imply irreversible kidney damage but need not be ignored. What Is Creatinine? Creatinine is produced from the normal metabolism of creatine, a substance found mainly in muscles. Because the kidneys remove it from the blood, a test for creatinine is often used as a measure of kidney function. A high level of creatinine in the blood may be a sign that your kidneys are not working as well as they should. But creatinine concentrations may also be influenced by muscle mass, age, diet, hydration, physical activity, and certain medications. Normal Creatinine Levels The normal range for creatinine may vary a little from lab to lab. Adult blood creatinine is typically about: Average level Men: 0.7–1.3 mg/dL Women: 0.6–1.1 mg/dL Children typically have a lower level as a result of their lower muscle mass. There is no single creatinine level chart that applies equally to everyone. Doctors interpret values based on age, sex, and muscle mass as well as on medical history and other kidney parameters. So, creatinine levels by age should be interpreted in context rather than just a number. 5 days ago Learn more
